Description

Technical Field

[0001] The utility model relates to the technical field of limestone production, in particular to a dust collecting device used for quicklime production. Background Art

[0002] Quicklime, also known as burnt lime, is mainly composed of calcium oxide. It is usually made by calcining natural rocks whose main component is calcium carbonate at high temperatures, which can decompose them into carbon dioxide and calcium oxide. In the production process of quicklime, a bag dust collector is required to purify the waste gas generated during the production process.

[0003] The existing Chinese utility model patent with reference announcement number: CN220110627U discloses a dust collecting device for quicklime production, which relates to the technical field of quicklime production, including a dust collecting box, a support frame and a dust exhaust port, the support frame is installed at the lower side of the dust collecting box, the dust exhaust port is arranged at the bottom of the dust collecting box, a partition is arranged inside the dust collecting box, the partition divides the dust collecting box into two upper and lower cavities, the lower cavity of the dust collecting box is connected to be provided with a dust inlet, the upper cavity of the dust collecting box is connected to be provided with a clean air outlet, a plurality of dust filter bags are installed on the partition, and cleaning components for cleaning the dust filter bags are arranged at both sides of the dust collecting box. The utility model can squeeze, crush and rub the calcium hydroxide condensed on the surface of the dust filter bag to separate it through the arrangement of the cleaning component and the driving component, thereby eliminating the steps of manually disassembling and cleaning the dust filter bag regularly, ensuring a longer continuous working time of the integrated device, thereby improving the efficiency of quicklime production.

[0004] The existing bag dust collection structure generally uses vibration to make the particles captured by the bag fall from the inside of the bag. The bag is prone to wrinkles due to its material. After long-term use, dust is prone to accumulation at the wrinkles of the bag, and vibration cannot effectively shake off the deposited dust. At the same time, the ash hopper of the existing dust collecting equipment is prone to compaction, which affects the discharge of accumulated dust. Utility Model Content

When the auger rotates, the dust inside the ash hopper is transported downward to the inside of the dust discharge port. This method can facilitate the discharge of compacted dust and prevent the dust from clogging the dust discharge port. BRIEF DESCRIPTION OF THE DRAWINGS
